Permo-Drive Hybrid Hydraulic Technology Offers Major Fleet Savings

02 December 2002

Permo-Drive Technologies Ltd. has developed a hybrid hydraulic drive system that can reduce fuel consumption for trucks and buses by up to 40 per cent, according to the recent SAE conference in Detroit.

""The potential impact of hybrid hydraulic systems on the economy in general and on commercial vehicle owners in particular could be significant,"" said Paul Chandler, Permo-Drive's vice president for North American Operations.

Speaking at an SAE Truck and Bus Meeting and Exposition earlier this month, Chandler said that Permo-Drive's Regenerative Drive System (RDS) can be applied to new or existing trucks. The RDS captures energy generated by a vehicle's braking process, then releases the energy back into the driveline as power is needed. Key design features include an innovative inline driveshaft, energy storage devices that utilize special composite materials, ultra-light-weight metals, and advanced hydraulic and electronic engineering.

Permo-Drive will begin testing the system in major North American vehicle fleets in 2003 and plans to make the technology available commercially by 2005.
